Sulfuric acid (H2SO4) erosion of new Lincoln Town Car
I bought a new Lincoln Town Car Signature L. I discovered 3 days later that the bottom side of the car appears to have been exposed to Sulfuric acid (H2SO4). This particular auto has a lot of aluminum. All of this, that can be seen, is eroded, turned chalky and white. The dealer finally agreed to replace some of the parts and extend the warranty. However, I bought a brand new car with only 21 miles on the odometer and I want the car replaced. My question is; will the erosion continue on the hidden parts, and parts not replaced. The entire front suspension frame is made from aluminum, also the transmission. Some of the engine metal parts are chalky white others show rust. Steel parts, such as the frame are rusted where the paint has been scraped away.
I appreciate anything, advice that you can give.
The "appears to have been exposed to Sulfuric acid" part is rather confusing, Jay. Do you mean to say that you think it actually was? If so you should certainly get a lawyer and insist on replacement. If you are merely picking a phrase to try to describe the appearance, I think you are obfuscating. What do the papers about the condition of the vehicle indicate?
I suppose it's vaguely possible that the car was on a lot or showroom floor that was treated with muriatic acid [affil link]. If so, you absolutely don't want that car.

Sounds like a car which has been very wet or in wet storage conditions. Think Katrina/Rita.
